Fig. 68. Invalid commissioning login
If the login is unsuccessful, the user can retry the login by tabbing back to the password digits using the left or right arrow
buttons and re-edit the password.
After a successful login the next commissioning page is automatically displayed (directed by the burner control module)
to setup one of these parameters depending on the model:
• Valve Proving (VP) when option – see next figure
• Postpurge time – see Fig. 71
When valve proving is supported in the burner control module the feature is enabled by specifying when it should occur:
• Not enabled (feature is disabled)
• Enabled prior to RUN (occurs prior to ignition trials)
• Enabled after RUN (after burner is running and before internal safety relay dropout state)
• Enabled before and after RUN (occurs at both times prior to and after RUN)
• Enabled half before & after RUN (high pressure test occurs prior to RUN and low pressure test occurs after RUN)
The setting is selected by scrolling these choices using the up and down arrow buttons (see Fig. 69). The current
parameter setting is displayed when the page is initially entered.
Fig. 69. Commission valve proving when option
The up and down arrow buttons are used to scroll through the choices on the edit line. The right and left arrow buttons are
used to tab to the save commands, “Yes” and “No”. When the input focus is on the save commands the up and down arrow
buttons scroll between “Yes” and “No”. When the choice is set to the desired value the “Yes” command is selected and the
OK button is pressed to commit the change. If the user decides not to save the choice and exit commissioning, the “No”
command is selected and the OK button is pressed.
When the setting is commissioned into the burner control module (“Yes” command is selected) the next page displayed is
one of the following (directed by the burner control module):
• Valve Proving (VP) time commission (when VP is not disabled) – see next figure
• Postpurge time commission (when VP is disabled and postpurge time is supported in BC) – see Fig. 71
• Valve Proving (VP) when confirmation (when VP is disabled and postpurge time is not supported in BC) – see Fig. 72
When valve proving is enabled in the burner control module the time duration of the test is configured (see Fig. 70).
NOTE: Tolerance on value proving timing value is
+/- 10%.
The current setting is displayed allowing the user to change it to a new value. This time parameter has a range of 0-63
minutes with times that must be set in the following manner:
• 0-60 seconds in 1 second increments
• 1-10 minutes in 10 second increments
•10-63 minutes in 1 minute increments
Because of these configuration constraints the minute and seconds digits increment/decrement in steps that force the
time into these allowed settings.
